I'm going to copy all the stuff from my existing main server that I want to keep onto the 2800.
Then make the 2800 a DC and presume if I then demote the existing DC this will give me the option to transfer all roles and global catalog master to a different DC which will be the 2800. Or is it better to transfer the roles before this stage?
Then I intend to rebuild the old DC and reintroduce it back into the domain as a DC. Is there going to be any problems if when I rebuild it I call it the same name? Shouldn't be any objects in AD relating to the old sid etc... when it's removed or will there be?
Trouble is at the moment it's had all the software installations from it so if I call it something different these definately won't work whereas keeping it the same they may still not work.
Originally I was going to try repartioning it but I feel a fresh o/s install would be better.
After I have got them both up and running going to then install the R2 upgrade on them.
